hi-
At the top of the gradient (mostly RNP) you'll see small (tRNA?) RNAs.
Then 18S rRNA, coinciding with the 40S subunit. both 18S and 28S are
present in subsequent fractions (even the one containing 60S, in my
experience). You may be able to see several other bands, by
EtBr and Methylene blue as well.
